For the record, Dancing with the Stars
pro Derek Hough
did not propose to his former partner and current girlfriend Shannon Elizabeth
. And she definitely did not turn him down.
"There's this whole weird rumor going around," the actress tells PEOPLE. "One of them says that he proposed and I said no, and the other says he proposed and I said yes, and we're getting married. Neither one is true."
Elizabeth denied the engagement rumors while playing poker for the One Step Closer Foundation in Inglewood, Calif., on Sunday. "Luckily he doesn't care. We were laughing about it," she says. "It's really funny."
Since coming in sixth place
, where she met her boyfriend, Elizabeth has been busy shooting a documentary and traveling. Hough, meanwhile, is preparing for the next season of the show. "Derek's going to get his new partner in a couple weeks," she says. "We have no clue who the costar's going to be. I'm hoping ... it's someone who's like 70, 80 years old."
Staying busy, Elizabeth says, is the secret to a successful relationship. "When you're both busy and you've got your own things, it's great because nobody's sitting around moping, waiting, hoping something will happen," she says. "We're both really happy and doing our own thing."
Does that mean she and Hough will be dancing their first dance -- as a married couple -- anytime soon?
"I don't know if we're ready for that," Elizabeth says, "but we're really happy the way we are."
